What is the main purpose of the Cartesian coordinate system?

The primary purpose of the Cartesian coordinate system is to provide a reference framework for a plane using x- and y-axes. This system allows for the precise representation of points, lines, and shapes within a two-dimensional space by defining their positions based on numerical values along the horizontal (x-axis) and vertical (y-axis) axes.

By establishing a clear and consistent way to denote locations, the Cartesian coordinate system is fundamental in various fields, including mathematics, physics, engineering, and computer graphics. It simplifies the process of graphing equations, analyzing geometric shapes, and solving problems related to space and distance. In short, it serves as a foundational tool for visualizing and working with two-dimensional relationships in a clear and organized manner.
